Question

Which of the following primary lymphoid organs is responsible for the maturation of B-lymphocytes?

Options

• Bone marrow

• Spleen

• Lymph nodes

• Thymus

Answer 1

Bone marrow is the primary lymphoid organ where B-lymphocytes are produced and mature into functional cells. As a primary lymphoid organ, the bone marrow serves as the origin site for all blood cells and is essential for generating mature B-cells that can recognize and respond to antigens before they are released into circulation.
